Abstract
The invention discloses a kind of decorative mortar using desulfurated plaster as base material, it is prepared from the following raw materials in parts by weight：20 30 parts of desulfurated plaster；20 25 parts of cement；45 55 parts of sand material；Strengthen 13 parts of ore deposit fiber；0.1 0.15 parts of cellulose；0.2 0.9 parts of retarder.The preparation method of the decorative mortar is to obtain mortar basestocks after above-mentioned raw materials are well mixed；The water of fixed amount is added according to the ratio of mud in mortar basestocks, decorative mortar is obtained after stirring 10 15min.The decorative mortar of the present invention has excellent water retention property as bedding mortar, while is incubated again, is heat-insulated, not ftractureing, not hollowing, easily construction, is a kind of extremely cheap green New Building Materials.
Description
Technical field
It is specifically a kind of using desulfurated plaster as the decorative mortar of base material and its preparation side the present invention relates to building material field
Method.
Background technology
A large amount of with flue gas desulfurization device put into operation, and generate substantial amounts of solid waste-desulfurated plaster.Solving work
Industry production process SO2While reducing discharge of waste gases, the research and application of carrying out desulfurated plaster comprehensive utilization of resources have important show
Sincere justice.Power industry is coal-fired rich and influential family, the SO that coal-burning power plant is discharged every year2Account for the 50% of national total release, wet type lime
Stone-gypsum is the fume desulphurization method that thermal power plant is most widely used, and this, which also has led to desulfurated plaster, turns into after flyash
The second largest solid waste of power plant afterwards, therefore realize that desulfurated plaster is comprehensively utilized instead of the natural gypsum and will have huge society
Meeting, economic benefit.
The surface of building and component surface and base material is applied to, protecting grassroots level is had concurrently and meets that requirement is made
Mortar, it can be collectively referred to as decorative mortar（Also referred to as motar）.Decorative mortar, which often divides two layers or three layers, is constructed：1. bottom
The effect of mortar is mortar is bonded securely with basic unit, should there is good water-retaining property.2. middle level primarily to levelling, has
When can save and not do.3. surface layer is mainly for smooth, the bright and clean ground surface effect of acquisition.Decorative mortar is mainly used in outside heat-insulation layer
Cracking resistance is protected, and decorative mortar should bond securely with basal plane, therefore it is required that mortar should have good workability and higher bonding
Power.Specifically, compared with masonry mortar, decorative mortar has the characteristics that：1. float coat is not subject to load；2. float coat with
Basalis will have enough adhesion strengths, make it in construction or conduct oneself with dignity for a long time and do not fall off, do not ftracture under environmental activity；3. smear
Surface layer is mostly thin layer, and is layered smearing, and surface layer requires smooth, bright and clean, careful, attractive in appearance；4. being used for dry environment, large area is sudden and violent
Dew is in atmosphere.
The content of the invention
The present invention is just to provide for a kind of new way of a large amount of solid waste comprehensive utilizations caused by flue gas desulfurization device
Footpath, proposes a kind of using desulfurated plaster as decorative mortar of base material and preparation method thereof, is economized on resources and the energy, protected with reaching
The purpose in retaining ring border.
Present invention employs following technical scheme.
A kind of decorative mortar using desulfurated plaster as base material, it is prepared from the following raw materials in parts by weight：Desulfurated plaster 20-30
Part；Cement 20-25 parts；Sand material 45-55 parts；Strengthen ore deposit fiber 1-3 parts；Cellulose 0.1-0.15 parts；Retarder 0.2-0.9 parts.
The desulfurated plaster is given up using gained solid after the sulfur dioxide in lime-coal-fired or oily flue gas of lime stone recovery
Slag.
Portland cement of the cement selection marked as 42.5Mpa.
The sand material selects the common yellow sand of 40-70 purposes.
The enhancing ore deposit fiber selects the acicular wollastonite fiber powder of 80-200 mesh.
The cellulose selects viscosity in 10000-40000Mpa ﹒ s TYLOSE 30000.
The retarder is sodium citrate and a certain proportion of mixture of boric acid.
The weight ratio of the sodium citrate and boric acid is 0.05-0.5：1.
A kind of preparation method using desulfurated plaster as the decorative mortar of base material, by desulfurated plaster 20-30 parts；Cement 20-25
Part；Sand material 45-55 parts；Strengthen ore deposit fiber 1-3 parts；Cellulose 0.1-0.15 parts；Retarder 0.2-0.9 parts, after being well mixed
Mortar basestocks；The water of fixed amount is added according to the ratio of mud in mortar basestocks, decorative mortar is obtained after stirring 10-15min.
The ratio of mud is 0.26-0.30.
Present invention obtains following beneficial effect.
The decorative mortar of the present invention is especially suitable for bedding mortar, and compared with other mortars, it more can be firm with basic unit
Ground bonds, and has excellent water-retaining property.The present invention is a kind of technical scheme of solid wastes recycling, and social and economic benefit is obvious,
Have broad application prospects.
